A late response, but I just saw your post:

I hope that you realize when I review any movie here - not just yours, what I say about video quality is meant to let people know what to expect before they download. I make a point not to criticize the contributor, unlike some reviewers. Those of us who post movies here are making a selfless act and, generally speaking, do the best we can with the materials and software we have. And, yeah, video encoding has a learning curve. Took me many months to get good at it, but I wasn't doing it that often, either. I've re-uploaded movies to provide better quality after having learned more. I wish I had the time and bandwidth to re-encode and re-upload some others. I'm glad you have been able to contribute movies (especially the hilarious 'The Eye Creatures' - oh yes, I said it!), and I hope you can continue to contribute.

I'm guessing that you use a Windows machine, so I can't help you with tips and the like.

Interlacing was created to display video on CRTs and minimize the number of frames broadcast. Interlacing refers to a common method for painting a video image on a display by displaying each line or row of pixels. This technique uses two fields to create a frame. One field contains all the odd lines in the image, the other contains all the even lines of the image. what you get when you rip a interlaced movie is horizontal lines appearing in the video, especially noticeable during motion. I use a program that allows for de-interlacing, which slows encoding. You don't always know if your source material is interlaced, so it's trial and error or always choosing de-interlacing during encoding.

Dual pass encoding is great for getting high video quality at a lower (1500kbps or below) bitrate. A lower bitrate often yields a smaller file.

The H-264 MPEG4 video codec is, in my opinion, currently the best for quality and small size, but requires more computing power, thus taking longer that other MPEG4 codecs.

An even later response,

so if I may inquire,

what tools do you use to De-Interlace and Duel Pass Encode

Thanks - Bill

I use the Mac program Handbrake mostly. I don't deinterlace; I inverse telecine when necessary. You can do 1- or 2-pass encoding with it.
